Data about Ophiuroidea

sexual dimorphism

Sexual dimorphism is a phenotypic difference between males and females of the same species. The prototypical example is for differences in characteristics of reproductive organs. Other possible examples are for secondary sex characteristics, body size and morphology, ornamentation and behavior.

integument differs between males and females. Includes the size, number, distribution or shape of cilia, scales, spines, hooks, bristles, feathers, hair, horns and teeth. Although not integmental structures, the antlers of mammals are included in this category because they are analogous in function to the sexually-selected horns and spines of other animals.

Carbon 13 isotopic signature. Enrichment or deficiency of the proportion of C13 isotope in a carbon source, relative to a standard proportion of 0.0112372 (found in the fossil source Pee Dee Belemnite). Expressed in per mil (‰). (http://en.wikipedia.org/wiki/%CE%9413C)

Nitrogen 15 isotopic signature. Enrichment or deficiency of the proportion of N15 isotope in a nitrogen source, relative to a standard proportion of 0.003663033 (found in air). Expressed in per mil (‰). (http://sisbl.uga.edu/stable.html#notate)

The date-time or interval during which an Event occurred. For occurrences, this is the date-time when the event was recorded. Not suitable for a time in a geological context. Recommended best practice is to use an encoding scheme, such as ISO 8601:2004(E).

The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.

The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.

The specific description of the place. Less specific geographic information can be provided in other geographic terms (higherGeography, continent, country, stateProvince, county, municipality, waterBody, island, islandGroup). This term may contain information modified from the original to correct perceived errors or standardize the description.

The full scientific name, with authorship and date information if known. When forming part of an Identification, this should be the name in lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term.

Nitrogen 15 isotopic signature. Enrichment or deficiency of the proportion of N15 isotope in a nitrogen source, relative to a standard proportion of 0.003663033 (found in air). Expressed in per mil (‰). (http://sisbl.uga.edu/stable.html#notate)

Carbon 13 isotopic signature. Enrichment or deficiency of the proportion of C13 isotope in a carbon source, relative to a standard proportion of 0.0112372 (found in the fossil source Pee Dee Belemnite). Expressed in per mil (‰). (http://en.wikipedia.org/wiki/%CE%9413C)

Some members of this lineage are simultaneous hermaphrodites; a condition of hermaphroditic animals (and plants) in which the reproductive organs of both sexes are present and functional at the same time.
